If my son had not put a Timney Trigger kit in his G19, that turned it in an earnest single action, I would have it out of my safe and checking that. I never knew that and would love to test it and see it in action, BUT, I simply don't have an Glocks of my own, and my son's is no longer the Glock "safe action".
Funny, discussing this with someone on another forum, I said it was a Hybrid Action because of the contradictions, and a mix of characteristics of both SA and DA, acts like single action, but what it is really doing is double action. I had a well informed Glock fan insist it is double action, because it meets the technical definition of DA, there is nothing Hybrid about it.
Can't win for loosing, but you should go on a Jeep forum and discuss 4 wheel drive terms and people with their own definitions and standards and then marketing terms that stretch the truth etc..... ....Manufacturers claim the weakest on road only AWD is 4WD, then you have Jeep fanboys insisting any system anything less the Wrangler Rubicon 4X4 Part Time transfer cases with no differential and locking front/rear differentials is NOT 4WD.
Meanwhile, I'm trying to explain its suspension that gives an off road vehicle its true off-road ability, and all I get is blank stares.
